11/19 Minor additions

Jonathan Mayo, MLB.com’s guru on Minor League players, offers this info on the two prospects whom the Cubs acquired from the Arizona Diamondbacks for Aaron Heilman:

Scott Maine, LHP: Taken in sixth round of the 2007 Draft of the University of Miami, Maine projects as a lefty reliever or specialist. He pitched at two levels in 2009, finishing with a 2.90 ERA and 61 K’s in 62 IP. For his career, he’s got a 3.29 ERA with a 134 K’s in 120 1/3 IP.

In some ways, the 24-year-old hasn’t lived up to the potential he once flashed in high school. He had Tommy John surgery early in his amateur career and never turned into the lefty ace some thought he’d be. That being said, he could have a future role. His fastball can run up to 93-94 mph and he comes from a pretty tough angle for left-handed hitters. He’s got a lower arm slot that creates some deception. His secondary stuff is is a work in progress, but the arm strength from the left side has some value.

Ryne White, 1B: White just completed his first full season of pro ball after being selected by Arizona in the fourth round of the 2008 Draft. An accomplished and advanced college hitter out of Purdue, White spent the season with Visalia in the Class Advanced California League, finishing the year at .266/.371/.356. He’s always shown an ability to control the strike zone and draw some walks, but he hasn’t hit for much power thus far in his pro career (career .389 SLG). There are those who feel the 23-year-old will hit for power going forward, at least as a left-handed platoon type. He’s kind of stocky, at 5-11, 205 lbs. At the very least, the Cubs are getting a decent organizational guy who has the chance to be a Matt Stairs type of hitter.

(My note: GM Jim Hendry said the same thing re: White, calling him a “Matt Stairs kind of guy.” As for Maine, Hendry said the D-Backs made a good decision to put him in the pen.)
